Insights

Higher operator experience in percutaneous coronary interventions with rotational atherectomy (PCI with RA) is linked to fewer complications. High-volume operators performing more PCI with RA procedures annually demonstrated better patient outcomes.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Health Services Research

Background:

  • Low operator and institutional volume in percutaneous coronary interventions (PCI) correlate with poorer procedural and long-term clinical outcomes.
  • This highlights a potential impact of experience on patient results.

Purpose of the Study:

  • To evaluate the association between operator experience and procedural outcomes in patients undergoing PCI with rotational atherectomy (RA).
  • To determine if higher operator volume impacts complication rates for PCI with RA.

Main Methods:

  • Utilized data from the Polish national registry of percutaneous coronary interventions (ORPKI) from January 2014 to December 2020.
  • Analyzed 5,188 PCI with RA procedures performed by 851 operators, categorizing operators by annual RA procedure volume.

Main Results:

  • Operators in the highest quartile of annual PCI with RA procedures (Q4: >11.57 procedures/year) showed a statistically significant reduction in overall periprocedural complications (p=0.019).
  • A nonlinear relationship was observed between annualized operator volume and risk-adjusted outcomes.

Conclusions:

  • High-volume rotational atherectomy (RA) operators are associated with a lower incidence of periprocedural complications compared to low-volume operators.
  • Increased operator experience, measured by annual procedure volume, is crucial for improving patient safety in PCI with RA.
